NAME

       cray.conf - Slurm configuration file for the Cray-specific information

DESCRIPTION

       cray.conf  is an ASCII file which defines parameters used by Slurm's select/cray plugin in
       support of Cray systems.  The file location can be modified at system build time using the
       DEFAULT_SLURM_CONF  parameter  or  at execution time by setting the SLURM_CONF environment
       variable. The file will always be located in the same directory as  the  slurm.conf  file.
       The default configuration parameters will work properly in a typical installation and this
       file will not be required.

       Parameter names are case insensitive.  Any text following a "#" in the configuration  file
       is  treated  as a comment through the end of that line.  Changes to the configuration file
       take effect upon restart of Slurm  daemons,  daemon  receipt  of  the  SIGHUP  signal,  or
       execution of the command "scontrol reconfigure" unless otherwise noted.

       The configuration parameters available include:

       AlpsEngine=<engine_version>
              Communication protocol version number to be used between Slurm and ALPS/BASIL.  The
              default value is BASIL's response to the ENGINE query.  Use with  caution:  Changes
              in  ALPS  communications  which are not recognized by Slurm could result in loss of
              jobs.  Currently supported values include 1.1, 1.2.0,  1.3.0,  3.1.0,  4.0,  4.1.0,
              4.2.0,  5.0,  5.1,  5.2 or "latest".  A value of "latest" will use the most current
              version of Slurm's logic and can be useful for  validation  with  new  versions  of
              ALPS.

       AlpsDir=<pathname>
              Fully  qualified pathname of the directory in which ALPS is installed.  The default
              value is /usr.

       apbasil=<pathname>
              Fully  qualified  pathname  to  the  apbasil  command.   The   default   value   is
              /usr/bin/apbasil.

       apbasilTimeout=<seconds>
              How many seconds to wait for the apbasil command to complete before killing it.  By
              default, wait indefinitely

       apkill=<pathname>
              Fully  qualified  pathname  to  the  apkill  command.    The   default   value   is
              /usr/bin/apkill.

       NoAPIDSignalOnKill=Yes
              When  set to yes this will make it so the slurmctld will not signal the apid's in a
              batch job.  Instead it relies on the rpc coming from the slurmctld to kill the  job
              to end things correctly.

       SDBdb=<dbname>
              Name of the ALPS database.  The default value is XTAdmin.

       SDBhost=<dbname>
              Hostname of the database server.  The default value is sdb.

       SDBpass=<password>
              Password  used  to access the ALPS database.  The default value is NULL, which will
              load the password from the my.cnf file.

       SDBport=<port_number>
              Port used to access the ALPS database.  The default value is 0.

       SDBuser=<user_name>
              Name of user used to access the ALPS database.  The default value  is  NULL,  which
              will load the user name from the my.cnf file.

       SubAllocate=Yes
              Only  allocate  requested  node resources instead of the whole node.  In both cases
              the user will be charged for the entire node.

       SyncTimeout=<seconds>
              Slurm does not normally schedule jobs while its job or node  state  information  is
              out  of  synchronization with that of ALPS. This parameter specifies a maximum time
              to defer job scheduling while waiting for consistent state.  The inconsistent state
              might  be caused by a variety of hardware or software failures and proceeding could
              result in more failures. The default value is 3600 (one hour). A value of zero will
              wait indefinitely for consistent state.
